MAX4888B/MAX4888C
Up to 8.0Gbps Dual Passive Switches
9
Detailed Description
The MAX4888B high-speed passive switch routes high-
speed differential signals such as PCIe, SAS, SATA,
and XAUI from one source to two possible destina-
tions or vice versa. The MAX4888B is ideal for routing
PCIe signals to change the system configuration. The
MAX4888C features a 10FA (typ) source current and
a 60kI (typ) internal biasing resistor to GND at the
AOUTA_, BOUTA_, AOUTB_, and BOUTB_ terminals.
The MAX4888C is ideal for circuits that are capacitively
coupled at both the output and input. These devices are
protocol independent and can be used to switch two dif-
ferent protocol signals over the same physical lane. They
feature dual digital control inputs (SEL, SELB) to switch
signal paths. SEL has a 70kI (typ) pulldown resistor to
GND and SELB has a 70kI (typ) pullup resistor to VCC.
These devices are fully specified to operate from a single
3.0V to 3.6V power supply.
Digital Control Input (SEL, SELB)
The devices provide dual digital control inputs (SEL,
SELB) to select the signal path between the AIN_, BIN_
and AOUTA_, BOUTA_ or AOUTB_, BOUTB_ chan-
nels. In most cases SEL is chosen and SELB is uncon-
nected. The truth table for the devices is depicted in the
Functional Diagram/Truth Table. SEL has a 70kI (typ)
pulldown resistor to GND and SELB has a 70kI (typ)
pullup resistor to VCC.
Analog-Signal Levels
The devices accept signals from -0.3V to (VCC - 1.8V).
Signals on the AIN+ and BIN+ channels are routed to
either the AOUTA+, BOUTA+ or AOUTB+, BOUTB+
channels. Signals on the AIN- and BIN- channels are rout-
ed to either the AOUTA-, BOUTA- or AOUTB-, BOUTB-
channels. The devices are bidirectional switches, allow-
ing AIN_, BIN_ and AOUTA_, BOUTA_, AOUTB_, and
BOUTB_ to be used as either inputs or outputs.
Applications Information
High-Speed Switching
The devices’ primary applications are aimed at sharing
resources. For example, a single lane of PCIe or SAS
can be shared between a single host and two devices.
This could be used for redundancy or to share resources
such as a physical lane or route a lane between one host
and two devices or two hosts and one device.
Board Layout
High-speed switches require proper layout and design
procedures for optimum performance. Keep controlled
impedance PCB traces as short as possible or follow
impedance layouts per the PCIe specification. Ensure
that power-supply bypass capacitors are placed as
close as possible to the device. Multiple bypass capaci-
tors are recommended. Connect all grounds and the
exposed pad to a large ground plane.
